Scalarworks PEAK/01 Fixed Rear Iron Sight

(Model SW1020)

Features

  • Precision Windage Adjustment – Exposed windage turret with crisp 0.5 MOA-per-click clicks, matching modern red-dot optic adjustments for seamless co-zeroing.
  • Ambidextrous Flip Apertures – Two same-plane apertures (0.07″ for precision, 0.20″ for speed) machined flat toward the shooter to eliminate highlight bias and provide rapid “circle-in-circle” target acquisition.
  • Optimized for 15″ Sight Radius – Center height of 1.42″ over Picatinny rail provides a correct sight picture on modern carbine-length AR-15 rifles.
  • Robust Construction – CNC-machined 7075-T6 aluminum body paired with 4140H steel hardware; Type III hard-coat anodize (aluminum) and flash-nitride (steel) finishes for superior corrosion and wear resistance.
  • Non-Rotating Sight Post – Flat-faced post prevents misleading reflections (“highlight bias”) even under bright lighting conditions.
